To answer your question: The dense outer boroughs of New York. New building or old, all it takes is one noisy neighbor to keep up half of the residents within a block. Loud noise is a notoriously difficult problem, and especially difficult to manage in a true mixing pot like NYC.

They meant well, but that sound carries. Yes, I told them to quiet down.
